Growing and Caring for the Biggest Venus Fly Trap


The Venus fly trap (Dionaea muscipula) is an extraordinary plant renowned for its unique appearance and carnivorous nature. Unlike other plants, it feeds on flies, making it an intriguing and captivating addition to any collection. Growing the biggest Venus fly trap requires proper care and attention. In this guide, we will explore the essential steps to cultivate and nurture this fascinating carnivorous plant.

Venus Fly Trap Overview

The Venus fly trap boasts an array of specialized leaves, often referred to as traps, which are designed to lure and capture insects. Each trap consists of two lip-like lobes connected by a hinge. Nectar within the trap entices unsuspecting insects, triggering the closure of the trap upon contact with trigger hairs. The trapped insect is then digested over several days, after which the trap reopens.

Venus Fly Trap Care

To successfully cultivate the biggest Venus fly trap, it is primarily grown as a potted houseplant. This enables close observation and provides optimal conditions for the plant’s unique behavior. While caring for this carnivorous plant may seem daunting, it follows similar principles to other houseplants with a few specific considerations.

Light Requirements

Place your Venus fly trap pot in a location that receives 12 hours of light per day during the growing season, which spans from spring to fall. Aim for at least 4 hours of direct sunlight within this duration to promote healthy growth.

Soil Composition

In its natural habitat, the Venus fly trap thrives in wet, acidic, and nutrient-poor soil found in bogs. To replicate this environment, use a peat-based potting mix with good drainage for indoor cultivation.


When watering your Venus fly trap, opt for rainwater whenever possible. Rainwater closely mimics the plant’s natural habitat and provides the ideal moisture content. If rainwater is unavailable, distilled water is a suitable alternative.


The Venus fly trap’s unique diet consists of live flies, mosquitoes, and gnats. Feed the plant by gently inserting these insects into the traps, ensuring they make contact with the trigger hairs. Keep a feeding schedule and track the number of times the plant opens and closes, as it has a limited lifespan for trap activation.

Flower Removal

To maintain the plant’s energy and focus on its carnivorous abilities, it is advisable to remove the flowers as soon as they appear. This prevents the diversion of resources toward seed production and ensures the plant’s vitality.

Propagation of Venus Fly Trap

The easiest and most reliable method to propagate the Venus fly trap is through division. Follow these steps:

  1. In early spring, mature plants produce offshoots. Using a sharp knife or pruners, carefully remove these offshoots, ensuring they include roots.
  2. Prepare pots measuring 4 to 5 inches in width and at least 6 inches in depth. Fill them with fresh peat-based growing medium, leaving a hole in the center.
  3. Plant the offshoots in the holes, ensuring they are adequately watered and the soil remains consistently moist.

4. Place the pots in an area with indirect light, avoiding direct sunlight until the offshoots develop new roots.

WARNING: Due to over-collecting and habitat destruction, the wild populations of Venus fly traps have significantly decreased. It is crucial to avoid wild harvesting and instead source plants from reputable nurseries that propagate their own specimens.

Potting and Repotting Venus Fly Trap

Venus fly traps require a soil mix that is more acidic than typical houseplant mixes. A combination of peat moss with soil mix or horticultural sand and peat moss works well, as peat moss helps acidify the soil. Sustainable alternatives such as wood-based materials (bark, sawdust, or wood fiber) with a low pH can also be used. Ensure the wood has not been chemically treated. Coir, although sustainable, is not suitable due to its close-to-neutral pH.

Avoid fertilizing Venus fly traps, as they thrive in low-nutrient soils similar to their natural bog environment.

For repotting, follow these detailed instructions to ensure the plant’s health and longevity.

Overwintering Venus Fly Trap

During the fall, Venus fly traps enter a period of dormancy as daylight hours decrease. The plant sheds its leaves, appearing dormant, but it survives underground through rhizomes. This is a normal part of its lifecycle, and artificial lighting should not be used to compensate for reduced daylight hours.

To overwinter your Venus fly trap:

  1. Keep the plant in the coolest room of your home.
  2. Reduce watering and maintain slightly moist soil without letting it dry out completely.
  3. As spring approaches and new growth emerges, resume regular watering to keep the soil consistently moist.

Common Pests and Plant Diseases

Despite their carnivorous nature, Venus fly traps can still face pest and disease issues. Aphids and fungus gnats may occasionally bother these plants, although they are too small to be captured and consumed. For severe aphid infestations, horticultural oil or insecticidal soap can provide control. Bacillus thuringiensis (BTI) can be used as a natural solution for fungus gnat control.

By following these care instructions, you can successfully grow and nurture the biggest Venus fly trap, delighting in its fascinating and unique characteristics. Remember to provide the specific conditions it requires, ensuring your plant thrives and continues its captivating insect-eating display.
